In golf, perfection is represented by a hole in one. I mean, even I know that. But recently I was fascinated to discover that most professional players don’t aim for that particular metric. Instead, they try to leave the ball stiff: a foot or so beneath the hole. This gives them a chance of an easy putt uphill, whereas if they try to be too precise, there’s a risk they end up above the hole with a more difficult downhill shot.
Occasionally, the ball will go straight in, but this is usually the unintentional result of a bad shot! Likewise, a less accomplished player will sometimes aim for the flag, but any direct hits will be greatly outnumbered by misses. That’s why you’ve never heard of the world record holder for holes in one (Texan player Mancil Davies has achieved 51 but has never got beyond journeyman status because of the erratic nature of his technique).
The point is that the top pros don’t aim for perfection every time. They aim to get 90% of the way there because they know that – over the course of a round, a tournament or a career – this will produce better results than shooting for 100%.
